Effects of Microcomputer Display on a Perceptual/Cognitive Task
The purpose of this study was to adapt the Hidden Figures Test (a measure of field dependence/independence) to microcomputer display and to assess its alternate form reliability when compared to a paper and pencil test. Participants included 58 undergraduate and graduate students (91.4% female) at a southeastern university who were fairly normal in regard to the task measured by the test. One group (N=38) was administered the print version of the test first, followed immediately by the computer version. The other group (N=20) received the computer version first to control for order effect. For the group who received the paper version first, the mean scores on both tests were equivalent (M=4.71); however, for the group receiving the computer version first, scores were significantly lower on the computer version (M=2.55) than on the paper version (M=5.20). The significant order effect found for the first group raises serious questions about the face validity of a computer version of the Hidden Figures Test, suggesting that additional research is needed before construct and face validity are assumed between alternative forms of test administration.
